Robotised Surface Impact Treatment

Proven Applications

Aeroengines and Turbochargers

New Parts: Blades (roots and airfoils); Blisks (IBR), Fans, Impellers; Compressor Wheels, Turbo Wheels; Bearings, Shafts, rotors; Disks (bores, sides, dovetails)
MRO: Blisks (IBR); Casing (welded areas); Disks, Fans (in-sit without disassembly)

Ground Turbines

New Parts: Blades (roots and airfoils); Shafts; Bearings; Rotor wheel (bores, sides, fin tree groove); Gears
MRO: Welded components; Disks dovetails (in-situ without disassembly); Rotor wheel

In-situ local Shot Peening

Ultrasonic Shot Peening uses the acceleration of a surface vibrating at 20 KHz to impart kinetic energy to the media.
Shot media are enclosed during the process within a hermetic chamber. Only few grams of highest quality media are required.


 Portable equipment for in-situ use with no or limited disassembly
 High surface quality – better than conventional shot peening
 Economical and Efficient
 Clean and Green
